Rating of Perceived Lower Extremity Function The participant will be asked to rate current perceived lower extremity function on a 100mm line anywhere between 'my function is at its worst' and 'my function is at its best.' The participant will rate by placing a vertical line that intersects the 100mm horizontal line perpendicularly. A standard metric ruler will be used to measure from the farthest left to the intersecting line. This distance will be recorded.
